Create your own piano

Here I used capacitor sensor through the Arduino pins but visually the sensor concealed. Here I included the capacitive sensor library in my arduino sketch that's why pins work as sensor. This sensor senses the human electrical capacitance, when a human body or hand touches the sensor. If you want to increase the sense of sensor, you can use medium to high value resistor. I recommend to micro ohm because, when your hand or bond moves away, some inches [ 4-5inches] the sensor will sense the electrical human capacitance from the human body
